John Joseph Costa, MD

Yeah, my name is, I'm not going to say my name. I have been with Dr. Costa for probably 30 years and he's very attentive. He listens and gives feedback. He's a very, very attentive doctor. I like going to him very much for those reasons. And that's it.

You are lucky to have him as a member of your team of physicians!

Mass General is nothing but the best! Thank you for absolutely everything that you do for me and for others!

Feels like he really cares about me and my issues even though he has so many patients. Always listens and if something isn't working tries to come up with something that will. Doesn't treat you like a number

Dr. Costa is an outstanding doctor. He's extremely concerning, thorough, kind. His follow-up, his conversation is 10 plus. I would highly, highly, highly recommend Dr. Costa to anyone that needs an allergist. He's great.

He's kind courteous, and a very good listener and he explains things to you in detail that you need to know when answers all your questions that you ask and that's what I like about him and I wouldn't change him for the world

Dr Costa has all the qualities I would seek out for a medical provider. He's professional, knowledgeable, caring, kind and friendly. He remembers me and knows my history with asthma. I wish more doctors had his level of caring and knowledge. I always look forward to my visits with him. Why? Because I like him!!??????

Dr. Costa is one of the finest gentlemen I have ever met. Not only is he a great doctor but also a real down to earth guy.

Dr. Costa has been my asthma care provider for several years. He is the most careful, caring doctor I have experienced in any setting. At the first apponitment, his questions about my medical history were detailed and perceptive, and I felt there was no limit on the amount of time I had available to express my concerns. He is never rushed or impatient. I am moving overseas, and will be sorry to say goodbye to him.

I just wanted to say a HUGE thank you...after a primary care visit and two urgent care visits, Dr. Costa was the first person to actually listen to me and have some idea of what the issue was. The inhaler was exactly what I needed. [redacted] He talked to me for 35 minutes in the office. He asked about all my medical history. He did the testing. And even when the testing showed my breathing was ok, he listened/believed me and gave me the inhaler and a back-up option to go on antibiotics if the inhaler didn't work by [redacted]. I felt SO SEEN. I had honestly thought I was just losing my mind and my anxiety was taking a new form or something because I couldn't get enough air for a month, but he didn't just chalk it up to my anxiety and he found a solution. I couldn't be happier!

Dr. Costa is one of my favorite doctors. Ever. He listens. He helped my chronic coughs basically disappear. And he ALWAYS runs on time. He is also the only person in the world who complements my nose, which makes me laugh and has become a little joke when I get home from my appointment. One more thing: you asked about nurses. I probably just saw medical assistants and not really a nurse. but they were excellent and my responses still hold true.
